Where a worker is injured on a journey home from a work-related function, fatigue and alcohol consumption associated with attendance at that function can constitute reasons connected with employment that materially increase the risk of injury under s.10(1C), even where the worker was also at fault through excessive speed. A finding that excessive speed was the sole cause of an accident is not open on the evidence where expert evidence places the speed below both the speed limit and the critical speed for the road, and unchallenged evidence establishes fatigue and alcohol as contributing factors. For s.10(1C), the material increase in risk must relate to the type of injury that actually occurred (obiter).
